Permanently redact text and images in a PDF

Draw boxes over sensitive text and we rasterize the page so the underlying content is genuinely removed. Free, in-browser.

Files are processed entirely in your browser. Nothing is uploaded to any server.

About this tool

Covering sensitive content with a black rectangle in a PDF editor is not the same as removing it. If the original text layer is still present under the box, anyone can select the covered area and copy the text out. True redaction requires that the underlying content be eliminated entirely. Redact PDF burns the selected regions into the page image using rasterization, so a copy-and-paste attack returns nothing.

To redact, open the PDF and drag rectangles over every region you want to remove — names, account numbers, addresses, signatures, or images. The boxes are previewed as grey overlays so you can confirm exactly what is covered before you commit. Once you click Apply, the affected pages are rasterized and the source content is gone. The resulting PDF also has its document metadata stripped.

Common use cases include preparing legal filings, sharing medical records with identifying information removed, publishing financial documents with account details hidden, and distributing contracts with third-party terms obscured. The entire redaction process runs in your browser, so the sensitive original content is never transmitted anywhere.
